One line of HTML. Your readers see exactly how much MRR they're losing to failed Stripe payments — without leaving your page. Free, no signup, no tracking pixels.
This is exactly what your readers will see:
Paste this anywhere that accepts raw HTML (Ghost, WordPress, Substack HTML blocks, Notion embed, Webflow):
<iframe src="https://recover-kit.com/embed/churn-calculator" width="100%" height="640" frameborder="0" style="border:0;max-width:560px;display:block;margin:0 auto;" title="SaaS Churn Calculator"> </iframe>
If you want the iframe to shrink/grow with the result panel instead of using a fixed height, drop this right after the iframe:
<script>
window.addEventListener('message', function(e) {
if (e.data && e.data.type === 'recoverkit-calc-resize') {
var f = document.querySelector('iframe[src*="recover-kit.com/embed/churn-calculator"]');
if (f) f.style.height = (e.data.height + 20) + 'px';
}
});
</script>
The calculator is built to slot into content about failed payments, churn, Stripe, pricing, unit economics, or retention. Good fits:
